Greetings all! Newbie1Kinobe here

I was given Studio 9+ plus for Christmas and everything works fine apart from the sound. It seems as if it has a warble to it by which I mean a high vibrato. It seems to be more noticeable on certain notes, whether it's music or speech.

I already have Studio 9 so I've uninstalled + and gone back to 9. It seems a shame because I really get on well with this program. I'm a complete novice so if anybody has any thoughts could you please explain it so I can understand? Thanks
